Auto-mock container: Rhino Mocks and NInject
Does anyone have an implementation lying around of an auto-mock container using Rhino Mocks 开发者_Go百科and NInject?
OK I built one myself using the Moq integration as a starting point. It is very simple. You need these 3 classes:
public class AutoMockingKernel : StandardKernel
{
private readonly IMockProvider _mockProvider;
public void Reset()
{
Components.Get<ICache>().Clear();
}
protected override bool HandleMissingBinding(Type service)
{
var isSelfBindable = TypeIsSelfBindable(service);
var binding = new Binding(service)
{
ProviderCallback = isSelfBindable
? StandardProvider.GetCreationCallback(service)
: _mockProvider.GetCreationCallback(),
IsImplicit = true
};
if (!isSelfBindable)
binding.ScopeCallback = ctx => null;
AddBinding(binding);
return true;
}
public AutoMockingKernel(IMockProvider mockProvider, INinjectSettings settings, params INinjectModule[] modules)
: base(settings, modules)
{
_mockProvider = mockProvider;
}
public AutoMockingKernel(IMockProvider mockProvider, params INinjectModule[] modules)
: base(modules)
{
_mockProvider = mockProvider;
}
}
internal class RhinoMockProvider : IProvider
{
public Type Type { get; private set; }
/// <summary>
/// Initializes a new instance of the <see cref="RhinoMockProvider"/> class.
/// </summary>
public RhinoMockProvider(Type type)
{
Type = type;
}
public object Create(IContext context)
{
return MockRepository.GenerateMock(Type, Type.EmptyTypes);
}
}
public class RhinoAutoMockProvider : IMockProvider
{
public Func<IContext, IProvider> GetCreationCallback()
{
return ctx => new RhinoMockProvider(ctx.Request.Service);
}
}
You can then create an auto-mocking kernel in your unit test like this:
[Test]
public void Test()
{
var kernel = new AutoMockingKernel(new RhinoAutoMockProvider());
... etc
}
There is a RhinoMocks integration extension available.
